In Boxing Chart, heart means a kind of thinking activity dominated by cerebrum, so in every action and movement, you must pay attention to direct your strength by concentration, and let internal energy control your movement, practice attentively in this way for a long time, remember any way constant effort yields sure success.Now you ‘ve already got a good knowledge about the combination of Qi and movement, in this phase , making your waist be axle, practice successively and Qi control your action regularly, requires you act in unison, once move, all move; once stop, all stop, all postures and movement should cooperate naturally, but in reality you may fail to coordinate all your activities, so this can affect the internal energy’s smooth flow and can’t make hands and body act in harmony and graceful system. In Boxing Secret, said “you must be attacked or hit ,if your hands fail to follow your movement of body, on the contrary you may hit your opponent easily just like cutting been curd with knife” .the saying illustrates that the cooperation between body and internal energy play an very important role in attacking and defense. There are still other unavoidable mistakes in this phase, for example, shoulder move first in hands-opening, do pay attention not have curve and crook movement, just straighten your back, but not stick out your chest. Under the premise of knowing essentials for each movement, gather the contradictions together, then crush one by one , don’t attend to one thing and lose sight of another, and naturally make your external movement match internal energy. In Ten Important Essentials in practicing Tai Chi Quan grand master Chen Chang-xing said “ heart go with will, Qi flow according with strength, the veins match with bones coordinating hands and feet, elbow go with knee, harmonizing shoulders and hip; left hand go with right foot, left, left elbow go with right knee, left shoulder go with right hip; head go with hands, hands go with body, body move with footwork, liver go with veins, spleen go with muscles, lungs go with body, kidney go with bone, in a word, once move, all move; once stop, all stop. In this phase, emphasis must be placed on the combination of thought and posture, and make your idea, thought, internal energy and external form in perfect harmony, thus your internal energy can reciprocate and repeat itself in endless cycle. Another point you should understand is that some opening-closing is partial display of the whole opening-closing, the general fault can be found through partial mistakes, so when adjusting ,you must pay attention to the whole body in the state of all-around body relaxation.

After this phase, you only reach the level of “20% Yin and 80% Yang, being new learner.”http://www.nickgudge.ie/5.c.viii.-method-for-practicing.html
